ABSTRACT

A tablet computer device comprises a overlay membrane detachably couplable to the tablet computer device to protect a display element of the tablet computer device, the overlay membrane having an integrated keyboard.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation of copending U.S. patent application Ser. No. 11/263,263, filed on Oct. 31, 2005, and incorporated herein by reference.

BACKGROUND OF THE INVENTION

Tablet computer devices are becoming increasingly popular. For example, tablet computer devices provide a portable and convenient computing solution with a display element for displaying content to a user and receiving input from a user (e.g., by an electronic pen and/or stylus). However, if the electronic pen and/or stylus should become lost, misplaced or inoperable, input to the tablet computer device 10 is more difficult. Additionally, in contrast to a notebook computer where a base member protects a display element when the notebook is closed, a display element of a tablet computer device is generally exposed and more susceptible to damage.

DETAILED DESCRIPTION OF THE DRAWINGS

The preferred embodiments of the present invention and the advantages thereof are best understood by referring to FIGS. 1-4 of the drawings, like numerals being used for like and corresponding parts of the various drawings.

FIG. 1 is a diagram illustrating an embodiment of a tablet computer device 10 and a overlay membrane 12 in accordance with the present invention. In the embodiment illustrated in FIG. 1, tablet computer device 10 comprises a display element 14 for receiving input from a user and/or displaying an output to a user. In the embodiment illustrated in FIG. 1, a housing 16 of tablet computer device 10 is configured to receive and/or otherwise be detachably couplable to overlay membrane 12 to facilitate protection of display element 14 by overlay membrane 12. For example, tablet computer device 10 and overlay membrane 12 are configured to cooperatively engage each other such that overlay membrane 12 is positionable over display element 14 to protect display element 14.

In the embodiment illustrated in FIG. 1, housing 16 of tablet computer device 10 comprises an elongate cavity 20 extending an entire dimension of tablet computer device 10 along a direction indicated generally by 22. As used herein, an “entire” dimension shall mean an entire dimension or substantially an entire dimension of tablet computer device 10. In the embodiment illustrated in FIG. 1, tablet computer device 10 comprises a connector element 24 disposed within cavity 20 for communicatively engaging overlay membrane 12. Connector element 24 may comprise any type of connector such as, but not limited to, a spring or biased element connector for engaging a corresponding connector element 30 disposed on overlay membrane 12.

In the embodiment illustrated in FIG. 1, cavity 20 is disposed along a side or peripheral location 32 of tablet computer device 10 and comprises an open end 34 and a closed end 36. However, cavity 20 may be otherwise located on tablet computer device 10 (e.g., on another side of tablet computer device 10). Further, in some embodiments of the present invention, tablet computer device 10 may be configured with multiple cavities 20 to facilitate detachably coupling of overlay membrane 12 to different locations of tablet computer device 10 (e.g., disposed on opposite sides, adjacent sides and/or all sides). It should also be understood that overlay membrane 12 may be detachably coupled to other non-side and/or non-peripheral locations of tablet computer device 10 (e.g., attachable to a rear or back portion of housing 16, front portion of housing 16, etc.).

In the embodiment illustrated in FIG. 1, overlay membrane 12 comprises a panel 40 having an integrated keyboard 42. Preferably, overlay membrane 12 is fabricated from a thin (in some embodiments of the present invention, ultra-thin), soft and/or flexible material to facilitate conforming of overlay membrane 12 to a shape and/or contour of tablet computer device 10 such as, but not limited to, leather or a pliable/deformable plastic material, and to provide a non-scratch cover for display element 14. In the embodiment illustrated in FIG. 1, overlay membrane 12 comprises an elongate member 50 having connector element 30 disposed thereon. Member 50 is configured to cooperate with cavity 20 of tablet computer device 10 to facilitate detachably coupling of overlay membrane 12 to tablet computer device 10. Connector element 30 communicatively couples keyboard 42 to tablet computer device 10 by communicatively engaging corresponding connector element 24 disposed within cavity 20.

FIG. 2 is a diagram illustrating partial engagement of overlay membrane 12 of FIG. 1 with tablet computer device 10 of FIG. 1, and FIG. 3 is a diagram illustrating full engagement of overlay membrane 12 of FIG. 1 with tablet computer device 10 of FIG. 1. As best illustrated in FIG. 2, elongate member 50 is inserted into open end 34 of cavity 20 and moved in the direction indicated by 60 relative to tablet computer device 10 to slideably engage overlay membrane 12 with tablet computer device 10. Preferably, a dimension of overlay membrane 12 and/or length of cavity 20 in the direction indicated generally by 62 is configured such that engagement of a corresponding end of elongate member 50 with closed end 36 when overlay membrane 12 is inserted within cavity 20 aligns and correspondingly engages connector element 30 of overlay membrane 12 with connector element 24 of tablet computer device 10 (FIG. 1). However, it should be understood that other methods may be used to provide alignment and/or engagement of connector elements 24 and 30.

As best illustrated in FIG. 3, overlay membrane 12 and tablet computer device 10 are movable relative to each other in the direction indicated by 70 to facilitate placement of panel 40 over display element 14 to protect display element 14. Further, as illustrated in FIG. 3, overlay membrane 12 facilitates keyboard 42 use with tablet computer device 10 by having keyboard 42 integrated within overlay membrane 12. Accordingly, embodiments of the present invention facilitate easy coupling of overlay membrane 12 to tablet computer device 10 to facilitate protection of display element 14 and/or use of keyboard 42 with tablet computer device 10.

FIG. 4 is a diagram illustrating another embodiment of overlay membrane 12 in accordance with the present invention. In the embodiment illustrated in FIG. 4, overlay membrane 12 comprises panel 40, a panel 80 and a panel 82. Preferably, panels 40, 80 and 82 are formed integrally with each other (e.g., formed as a unitary structure), thereby providing portfolio-type cover. However, it should be understood that overlay membrane 12 may be otherwise manufactured. In the embodiment illustrated in FIG. 4, overlay membrane 12 facilitates at least partial enclosure of tablet computer device 10 within overlay membrane 12, thereby providing additional protection of tablet computer device 10. For example, in the embodiment illustrated in FIG. 4, panel 80 is configured to extend along a rear surface 86 of tablet computer device 10, and panel 82 is configured to extend slightly beyond a side or top portion 88 of tablet computer device 10 such that when panel 40 of overlay membrane 12 is disposed near or against display element 14, panel 82 is extendable downwardly to engage at least a portion of panel 40 (e.g., an outer surface 90 of panel 40) to releasably secure panel 82 to panel 40 (e.g., using hook-and-loop fasteners or otherwise 92). Thus, panels 40, 80 and 82 are configured to extend about an entire perimeter of tablet computer device 10 in at least one direction to enclose tablet computer device 10 within overlay membrane 12 to protect tablet computer device 10 and also enable keyboard 42 use therewith.

Thus, embodiments of the present invention provide a thin, protective overlay membrane 12 for protecting display element 14 of tablet computer device 10 and enabling use of a keyboard 42 with tablet computer device 10. Embodiments of the present invention facilitate easy attachment and detachment of overlay membrane 12 to tablet computer device 10, thereby providing flexible use of overlay membrane 12 and/or tablet computer device 10.
